1. Crank your oven to 350°F (175°C). Grease a 9×13-inch baking dish with cooking spray or butter—don’t skip this step.
2. Cook the elbow macaroni in a large pot of salted boiling water according to package directions until al dente (slightly firm). Drain well but don’t rinse. Set aside.
3. While the pasta cooks, heat a large skillet over medium heat. Add the ground beef and cook, breaking it up with a wooden spoon. Let it sit for a minute at a time to get a nice brown crust—this adds flavor.
4. Once the beef is mostly browned, add the diced onion and minced garlic. Cook for another 5-7 minutes until the beef is completely done and the vegetables are softened. Drain off any excess fat by tilting the pan and spooning it out.
5. Stir in the diced tomatoes (with their juice), cheddar cheese soup, milk, and 1 cup of the shredded cheddar cheese. Season generously with salt and pepper—taste it and adjust until it tastes really good. This sauce should be flavorful on its own.
6. Add your cooked macaroni to the skillet and stir everything together until the pasta is completely coated in the cheesy beef sauce. Make sure it’s well mixed.
7. Transfer the entire mixture to your prepared baking dish and spread it out evenly. Sprinkle the remaining 1 cup of shredded cheddar cheese all over the top.
8. Cover the dish with foil (spray the underside with cooking spray first so cheese doesn’t stick) and bake for 20 minutes.
9. Remove the foil and bake for an additional 10 minutes, or until the cheese on top is melted, bubbly, and starting to brown in spots.
10. Let it rest for about 5 minutes before serving—this helps everything set up. Garnish with chopped fresh parsley if you’re feeling fancy. Serve hot and watch it disappear.

Notes:

• Don’t overcook the pasta initially—it continues cooking in the oven and you don’t want mush.
• Drain the ground beef really well or your casserole will be greasy.
• Shred your own cheese from a block. Pre-shredded cheese melts weird because of anti-caking agents.
• Season the beef mixture generously—underseasoning is the most common mistake.
• Every oven runs differently, so check at 25 minutes total to make sure the cheese isn’t burning.

Storage Tips:

Store leftovers covered in the refrigerator for up to 4 days. Reheat individual portions in the microwave for 2-3 minutes, stirring halfway through. To reheat the whole casserole, cover with foil and warm in a 350°F oven for 20 minutes. This casserole freezes beautifully—assemble completely but don’t bake, then wrap tightly in plastic wrap and foil. Freeze for up to 3 months, thaw overnight in the fridge, and bake as directed (adding about 10 extra minutes to the covered baking time).

Serving Suggestions:
